Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 3 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 247 Potential security issue detected. Manual review is recommended.Fix: Review the flagged content for security risks. Ensure no credentials, secrets, or sensitive data are exposed.
- high Tool Misuse · line 322 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
- medium Privilege Escalation · line 25 Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.Fix: Avoid sudo/root unless strictly required. Prefer least-privilege patterns. If elevation is needed, document the justification and scope.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00025 | $0.02991 |
| Opus 5 | $0.00013 | $0.01496 |
| Sonnet 5 | $0.00005 | $0.00598 |
| Haiku 4.5 | $0.00003 | $0.00299 |
Grade B, and why
block-storage scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Block Storage
Manage block storage volumes including LVM, cloud-based EBS, filesystem creation, snapshots, and RAID configurations. Covers the full lifecycle from provisioning raw disks to extending volumes in production.
When to Use
- Adding, partitioning, or formatting new disks on Linux servers
- Managing LVM logical volumes for flexible storage allocation
- Provisioning and attaching cloud block storage (AWS EBS)
- Creating and restoring snapshots for backup or migration
- Configuring software RAID for redundancy or performance
- Extending existing volumes without downtime
Prerequisites
- Root or sudo access on the target system
lvm2package installed for LVM operationsmdadmpackage installed for software RAID- AWS CLI configured for EBS operations
- Understanding of the workload's I/O characteristics (IOPS, throughput)
Disk Discovery and Partitioning
# List all block devices
lsblk
lsblk -f # Show filesystem types and mount points
# Show detailed disk information
fdisk -l /dev/sdb
# Identify disk model and health (requires smartmontools)
smartctl -a /dev/sda
smartctl -H /dev/sda # Quick health check
# Create a GPT partition table and a single partition
parted /dev/sdb mklabel gpt
parted /dev/sdb mkpart primary ext4 0% 100%
# Alternative: use fdisk for MBR partitioning
fdisk /dev/sdb
# n -> new partition, p -> primary, Enter defaults, w -> write
# Inform the kernel of partition table changes
partprobe /dev/sdb
# Wipe filesystem signatures (prepare for LVM or RAID)
wipefs -a /dev/sdb1
Filesystem Creation and Management
# Create an ext4 filesystem
mkfs.ext4 /dev/sdb1
# Create an ext4 filesystem with label and reserved block tuning
mkfs.ext4 -L appdata -m 1 /dev/sdb1 # 1% reserved blocks (default is 5%)
# Create an XFS filesystem (recommended for large volumes)
mkfs.xfs /dev/sdb1
# Create an XFS filesystem with label
mkfs.xfs -L appdata /dev/sdb1
# Mount the filesystem
mkdir -p /data
mount /dev/sdb1 /data
# Add persistent mount to fstab (use UUID for reliability)
blkid /dev/sdb1 # Get the UUID
echo 'UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx /data ext4 defaults,noatime 0 2' >> /etc/fstab
# Mount all entries in fstab
mount -a
# Check and repair a filesystem (unmount first)
umount /data
fsck.ext4 -y /dev/sdb1
xfs_repair /dev/sdb1 # For XFS
# Resize ext4 (can grow online while mounted)
resize2fs /dev/sdb1
# Resize XFS (must be mounted to grow)
xfs_growfs /data
# Check filesystem usage
df -hT
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

block-storage is a skill published in the GitHub repository BagelHole/DevOps-Security-Agent-Skills (1,084 stars, last pushed 3mo ago), licensed MIT. It adds 25 tokens to every session and 2,991 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
